- srmnnr. non DUPLICATING-MACHINES Aim rnnrixn Specification ofLetters Patent. P t t d May 10, 1921 Application filed October 4, 1917, Serial No. 194,822. Renewed February 18, 1921; Serial No. 446,107.

To all whom it may concern:

Be it known that I, ALBERT IsAA'os, a citizen of the United States, and a resident of the borough of Queens, in thecity and now known in the art and whichmay be easily and quickly removed and replaced in a reversed posltion as hereinafter particu- -larly explained.

. The invention consists in the novel construction, arrangement and combination of elements and parts, as shown in the accompanying drawings and hereinafter more particularly described;

In the said drawings, Figure 1 is a side viewof one form of my improved spindle, the same being broken away at its central portion;Fig. 2 is a longitudinal section of the same; Figs; 3 and 1 are detail views to be hereinafter described; Fig. 5 is an end view; Fig.8 is a side view of the same, showing one manner of securing the same to a duplicator;'and Fig. 7 is a fragmentary view showing a modified form of supportin means for said roller.

n carrying myinventioninto effect in the embodiment thereof which I have selected for illustration in the accompanying drawings and description in this specification I provide a tube 11 of wood or suitable material, open at both ends. A rod 12 is also provided, adapted to slide in the other is recessed asshown at 14, at various points on its periphery, the faces of these recesses being flush with the outside of the tube 11 when the disks 13 are in place. At the center of each disk 13 I provide a square p'erfo-- ration 15. V V

I provide capsldstamped out of sheet metal or the like, the form of which is particularly shown in Fig. 4, and which are adapted to fit over the disks 13, and'secure them in place over the tube 11. Each of these caps 16 1s providedwith a central square perforation 18 adapted to coincide and caps 16 are in place; and-is also provlded wlth'securing members 17, adapted to be bent inward over the disks 13, to pass through the recessesl l, and along a portion ofv the tube 11, to which they may be secured by means of screwsor tacks 22, pass- ,ing through suitable perforations 21 there- .-1n,-. and into the materlal of the tube 11.

In duplicating machines of the types with which 'myimprove'd: spindle is adapted to be used, it is desirable to provide a-suitable frame, comprising upright portlons, such with theperforations 15- when the disks 13 as those designated 23 and 2 1 in Fig. 6, be- 7 tween which the spindles carrying the-duplieating. medium areadapted to be j ournaled. Anysuita'ble means for securing the roller or spindle in place may be provided, but for the purpose of illustration I- have shown the member 23 provided with a slot, indicated at 25 bydotted lines (see. Fig. 6) and on the outside of the member 23 I show a downwardly extending springstrip 26 secured at 27 to the member 23: above the slot '25, this strip 26 being provided at its lower end with a perforation. adapted to receive the outer end of the pins 19. J ournaled in the member 24: Ihave shown a crank 28, provided, as is usual in such constructions, with a ratchet 29 having a pawl 30 adapted to engage therewith. On the inner side of the member, and connected with the crank 28, is a square chuck member adapted to fit into the openings 18' and 15. This. chuck member is designated 31, and is shown in dotted lines in Fig. 6.

In use, either end of the spindle may be inserted over the chuck 31, which enters the spindle through the perforation 18, and bears against the end of the pin 19, which 'it forces into the interior of the tube 11,

thus forcing the portion 20 at the opposite end of the rod 12 outward into the perfora tions 15 and 18, so that the pin 19 at said opposite'endwill project from the tube 11. In placing the end of the spindle over the I chuck 31, the spindle is so held that when the pin 19 at the opposite end is pushed out,

' it will project into the slot 25 in the member 23. The end of the pin 19 may then be easily slipped into the perforation in the lower end of the spring 26, the portion of the member 23 above the opening 25 hold- ,ing the spindle from slipping off the portion of which is shown in Fig. 7.

It is obvious that my improved spindle vmay not only be used in connection with various forms of duplicators, but also with machines and apparatus intended for various other purposes, indeed it maybe usefully employedwherever it is desirable to provide 'a spindle or roller which is required tobeeasily-and quickly reversed end for end for any purpose whatever and still in either position be adapted tov be rotated to roll up material stored thereupon orfor any other reason.

r The advantages of my invention will be obvious from what has been above set forth concerning its construction and mode of operation. do not limit myself to the exact construction shown and described, as it will be evident that various; departures might be made therefrom, without departing from the spirit and scope of my invention. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

1. In a spindle, the combination with a a downwardly extending spring tube adapted to have rolled or stored thereon a duplicating film or the like and provided at each end with a chuck-engaging member; of a shaft shorter than said tube and extending longitudinally therethrough andslidable therein,'whe'reby only one end of said shaft may always project from said tube and form a bearing pin upon which that end of the spindle'may rotate, whereby said spindle is adapted to be interchange ably reversed end for end, substantially as herein set forth.

2. In a spindle, the combination witha tube adapted to have rolled or stored thereon a duplicating film or the like and provided at each end with a chuck-engaging member; of a shaft extending longitudinally therethrough and'slidable therein, whereby one end only of said shaft may project from said tube when placed in position and form a bearing pin upon which that end of the spindle may'rotate, the entire remaining portion of said shaft being contained within said tube; whereby said spindle is adaptend, substantially as herein set forth.

3. ,In a duplicator, the combination with prising a tube adapted to have rolled or stored thereon a duplicating film or the like and provided at each end with a, chuckengaging member adapted to engage with said chuck, and a shaft extending longitudied to be interchangeably reversed end for,

nally through said tube and slidable there- H in, whereby one end only ,of said shaft may project from said tube when placed in position and form a bearing pin adapted to engage with said bearing. in the frame and upon which that end of the spindle may rotate; whereby said spindle is adapted to be interchangeably reversed'end for end substantiallv as herein set forth. V

In witnesswhereof I have hereunto signed my name this 29th day of September, 1917.

It is hereby certified that in Letters Patent No. 1,377,584, granted May 10,

1921, upon the application of Albert Isaacs, of New York, N. Y., for an improvement in Spindles for Duplicating-Machines and the like, errors appear in the printed specification requiring correction as follows: Page 2, line 18, for the nilineral 28 read 128, and line 20 for the numeral 29 read 129, and that the said Letters Patent should be read with these corrections thereinv that the sanie may conform to the record of the case in the Patent Office.

Signed and sealed this 14th day of June, A. D., 1921.
